Energy Efficiency and Historic Buildings - Application of Part L of the Building Regulations to historic and traditionally constructed buildings

Front cover for Energy Efficiency and Historic Buildings

Part L of the Building Regulations seeks to improve the energy efficiency of all buildings. For existing buildings, including historic buildings and those of traditional construction, this means reducing heat losses wherever possible without damaging their special character or compromising their performance.

This fully illustrated guidance has been produced to help prevent conflicts between the requirements of Part L of the Building Regulations and the conservation of historic and traditionally constructed buildings.

The advice acts as 'second tier' supporting guidance in the interpretation of Approved Documents L1B and L2B that should be taken into account when determining appropriate energy performance standards for works to historic and traditionally constructed buildings.

The following areas are covered in the guidance:

  • The background to the legislation and the need to reduce greenhouse gas emissions
  • An interpretation of the regulations themselves as applied to historic and traditionally constructed buildings
  • Understanding the buildings before carrying out upgrading works
  • Meeting the requirements of Part L
  • Advice on the thermal upgrading of various building elements

The guidance supersedes English Heritage's previous publication Building Regulations and Historic Buildings an interim guidance note on the application of Part L (2004).

On 1 April 2015 the part of English Heritage represented on this website changed its name to Historic England. You may notice that some of our content still refers to English Heritage. We are in the process of rebranding, but in the meantime please be assured that all our content and guidance is still current.
